such as will enable-others skilled in the art to which it appertains to make-and use the same.

- This'invention relates to new" and useful improvements 1 inroofing-tools, and has for its principal object to'providea simpleand efli'cient tool for forming the standing seams.

Heretofore inthe forming of roofingseams it has been the practice for the tinner or person placlng the roof I 1n posit-1on to use a 1 pair of tongs for first bending over the wider upstanding edge of the tin and then to use a mallet or hammer to 'bendthe same downwardly in position for the finishing and then after the hammering process is completed,

" to use'a pair of tongs to force'the joints down tight in order to prevent any leakage. My invention has for its principal ob ect to eliminate the necessity of theuse of more than onetool to complete the=entire'opera- -tion.

With the aboveandotherobjec'ts in view, the invention consists in the novel combination' and" arrangement of parts which w1ll be fully set forth in the following specifica tion and accompanying draw1ngs,1n"-wh1ch,

The member 1 is provided "at its upperendivith a suitable D handle 4 and at its lower'end with the arcuate extensione. Thls 'arcuate extension is provided at its freeend with the lateral pro-jection6 to which the "bolts 7, which hold the elements illustrated in Figs. 8 and 10in operative position, aresecu'red.

These elements whichareillustrated 111 Figs-Sand 10 form one jaw of the-tongs and comprise the substantially triangular body cylindricalfportions "9 and the element 13;

Thesecylindrical portions are formed with the central longitudinal apert ures 10 and are arranged to cooperate with the cylindrical portions-=11, having the central longitudinal apertures "12"for1ned therein, insupporting the coiiperati ng" element' 13" in position;

Each of theseelements 8 and 13 is provided with 'a diagonally extending aperture 1 1 8' having formed at one edge a plurality of:

near each end, and a suitable' 'coil spring 15 is-secur'ed within theia erau-e and is arrangedto remain under tension-so that the elements "will be held in the position illus trated in Fig. 10when in their normal posi- 111011; A suitable pivot pin '16is arranged' to extendthrough the apertures 10 and 12 to held the elements in'th'e'ir proper rela' The cooperating element comprises the cylindrical handle-'17 having formed at its upper-end the T gripping portion 18, andthe 'lowerend' of this handle'is reduced as at 19and rotatably mounted in the bodydesignated generally] by the numeral 20. This body 20 oompr-i'ses the two'cooperating elements-21 and 22, which elements coeperate I with each other-in forming the-yj aw jopposite! the jaw hereinbefore referred to.

The

ele'ment21 is provided-with a-plural-ity of screw threaded apertures and has" :formed integral therewith the downwardly extending portion 23 w'hich terminates in the hook portion24.; This body 21 is provided with" thesemicircul ar recess 25 which cooperates with therecess 26 formed "in the body portion '22 to form abearing in which the remounted-.- The body 22 'hereinbefore referred to is provided with the laterally extending fiang'es27 through which the bolts,

which extend" into the threaded recesses duced end 19 of the-handle"17'is rotatably' formed in the body 21, project, and these flanges are arranged to cooperate witlrthe I extension 30 on which the hinged portion 31 indicated at A and B in Fig. 3, is placed in' 3, l, 6 and 7.

is hingedly secured as at 32. This hinged portion has secured to its upper surface the U-shaped plate 33, one of the arms of which is connected to the link 3a, the opposite end of which link is pivotally connected by the screw eye 35 to the rotatable handle 17. The opposite arm of the U-shaped plate is connected to the tension coil spring 36, the opposite end of which is secured to the staple or other suitable support 37 so that the spring is at all times under tension. It will thus be seen that the element 31 will be supported in the position illustrated in Figs.

In order to prevent the element 31 from swinging beyond a predetermined point, suitable stop members 38 are provided at each end of the device, and it will thus be seen that the member 31 will be held in a plane substantially at right angles .to the member 29.

. From the foregoing it will be apparent that when it is desired to make use of the device, the tin, which has been previously prepared by bending the edges upwardly as position and the device is positioned as illustrated in said figure so that the element 31 engages the deeper bend A. Upon pulling the handle apart it will be apparent that the two cooperating members will swing on,

their pivot 3, thereby causing the element 31 to engage the extension of the bend A, thus causing the same to assume the posltlon illustrated in Fig. 4c. After this operation the T handle 18 is turned which will cause the shaft 17 to rotate within its bearing and thereby cause the link 34, which is pivoted to the U-shaped plate 33, to force the member 31 downwardly in the position illustrated in Fig. 5. In forcing this member 31 downwardly it will be evident that the free end of the bent-over portion A will be forced into the position illustrated in Fig. 5 and be ready for the final clamping i action which is accomplished with the same tool. After the tin is in the position illustrated in Fig. 5, the jaws are opened by forcing the handles toward each other and the T handle is still held in its turned position. This will cause the two members 8 and 13 to swing on their pivots so that the Qopies of this patent may be obtained for member 8 will pass beneath the free edge of the tin and after having passed that point, will again spring to its normal upward position, and the device is then ready for the final clamping action which is accomplished after the handle has been released so that the member 31 will spring upwardly into its normal position through the action of thespring 36. The handles are then again forced apart which will cause the member 8 to engage the free edge of the tin and force the same firmly against the portion B, thereby causing the joint to assume the position illustrated in Fig. 7 thus completing the same without necessitating the use of more than a single tool and also without moving the tool from its position on the roof.

It will be clearly seen that with the use of a tool of this character the roofing of buildings may be easily and quickly accompllshed at a minimum expenditure of time and labor, and a particularly simple and eflicient tool is provided which may be easily and cheaply constructed.

/Vhile in the foregoing there has been shown and described the preferred embodiment of this invention, it is to be understood that such changes may be made in the combination and arrangement of parts as will fall within the spirit and scope of the invention as defined in the appended claims.

What is claimed is:

1. A roofing tool comprising a pair of tongs, jaws carried by the tongs, one of the handles of one of the jaws being rotatable with relation thereto, bending elements carried by the jaw in which the rotatable handle is mounted means connecting the bending elements with the rotatable handle to cause the elements to bend when the handle is rotated, and a mandrel carried by the cooperating jaw and arranged to form a cooperating bending element.

A roofing tool comprising a pair of tongs, jaws carried by the tongs, bending elements carried by one jaw, a rotatable handle in the jaw on which the bending element is mounted, means connecting the bending elements with the rotatable handle, whereby when the handle is rotated the elements are actuated, and a jointed mandrel carried by the other jaw and arranged to form a cooperating bending element over which the material which is being bent is forced by the bending elements.

In testimony whereof I afiix my signature in presence of two witnesses.
